Disney develops 'feel-around' touchscreens

Lucas Mearian | Oct. 10, 2013
Disney announced a new touch-screen technology prototype that offers users tactile sensations that mimic real surfaces.

"We first determined a psychophysical relationship between the voltage applied to the display and the subjective strength of friction forces, and then used this function to render friction forces directly proportional to the gradient (slope) of the surface being rendered," the researchers stated in a news release.

The researchers said a comparison study showed that users are at least three times more likely to prefer the proposed slope-model than other commonly used models of tactile touchscreens.

"Our algorithm is concise, light and easily applicable on static images and video streams," the researchers stated.
